Purpose: Behavior and temperament (e.g., emotional reactivity, self-regulation) have been considered relevant to stuttering and its developmental course, but the direction of this relation is still unknown. Knowledge of behavior difficulties and temperament in childhood stuttering can improve screening and intervention. The current study examined…

Although the Child Behavior Checklist 1½-5's 12-item "Diagnostic and Statistical Manual of Mental Disorders"-Autism Spectrum Problems Scale (formerly called Pervasive Developmental Problems scale) has been used in several studies as an autism spectrum disorder screener, the base rate and stability of its items and its measurement model…

Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

The Strengths and Weaknesses Heuristic (S&W Heuristic) was constructed in order to reduce biased assessments of students with (suspicion of) Intellectual Giftedness in co-occurrence with Autism Spectrum Disorder (IG + ASD) and to establish a well-founded interconnection between assessment data and intervention indications. The current study is…

The aim of this study was to evaluate the effectiveness of a computer-based executive function (EF) training in children with specific language impairment (SLI). Ten children with SLI, ages 8 to 12 years, completed a 25-session training of visuospatial working memory, inhibition and cognitive flexibility over a 6-week period. Treatment outcome was…

Enhancing communication performance skills may help children with Down Syndrome (DS) to expand their opportunities for participation in daily life. It is a clinical challenge for speech-language pathologists (SLP) to disentangle various mechanisms that contribute to the language and communication problems that children with DS encounter. Without…

Individuals with autistic traits are considered to be prone to develop psychosexual problems due to their limited social skills and insight. This study investigated the longitudinal relation between autistic traits in childhood (T1; age 10-12 years) and parent-reported psychosexual problems in early adolescence (T2; age 12-15 years). In a general…

In this paper, (1) the psychosocial health in relation to (2) life-events was assessed among 156 children attending 20 schools by parents and teachers with the Child Behavior Checklist and the Caregiver-Teacher Report Form at the ages of four and six. Life-events were reported by parents. (1) According to the report, 93-96% children had no…

Agreement among informants' ratings of children's and adults' internalizing and externalizing problems is moderate. Each informant contributes unique information about an individual's problems. Thus, it has been advocated to obtain ratings from multiple sources in child psychiatry, whereas adult psychiatry relies mostly on self-reports.…

This study examines the concurrent and longitudinal relationships between reactive and proactive aggression and children's peer status. Participants were 94 Dutch elementary school-aged boys in self-contained special education classrooms for students with emotional/behavioral disorders (EBD) and 47 boys with no disabilities in general education…

High and stable levels of aggression and the presence of aggressive behaviour in multiple settings according to different informants are risk factors for later problems. However, these two factors have not been investigated in early childhood. The present study investigates trajectories of parent-reported child aggression from 1.5 up to 6 years of…

Objective: To examine externalizing behavior problems and cigarette smoking as predictors of subsequent cannabis use. Method: Dutch adolescents (N = 1,606; 854 girls and 752 boys) from the TRacking Adolescents' Individual Lives Survey (TRAILS) ongoing longitudinal study were examined at baseline (ages 10-12 [T1]) and at two follow-up assessments…

Accelerated longitudinal analyses of 7 cohorts of Dutch children over a 10-year period were used to determine whether longitudinal data on children in 1 cohort could predict outcomes of psychopathology in another. Results support accelerated longitudinal analysis to combine short-term longitudinal studies of behavioral-emotional problems into a…

Comparison of scores on the Child Behavior Checklist of 1,120 Flemish and 1,122 Dutch children, aged 6 to 12 years, found no differences between groups on total problem scores, higher scores for Dutch children on the Activities scale, and higher scores for Flemish children on the School scale.

Principal factor analysis and promax rotations were performed on Child Behavior Checklist (CBCL) scores of 2,339 clinically referred Dutch children. Dutch syndromes were very similar to the CBCL cross-informant syndromes derived by T. M. Aschenbach (1991), supporting the cross-cultural generalizability of the CBCL cross-informant syndromes. (SLD)
